摘要
本文用变化力作用下有效变形模量和收缩徐变微差概念计算未裂钢筋混凝土构件的时随变形,从而为长期作用下的非弹性时效问题化为弹性问题处理开辟了道路。通过例题计算比较,本文所取方法,物理意义明确,结果符合得很好。
In this paper with the effective modulus of deformation on action of changeable force and the
concept of differential shrinkage and creep long-time stresses and deformation of not cracked reinforced
concrete member,by the method of long-term effective coefficient of rigidity time-ependent deflection
of cracked reinforced concrete memeber are calculated,then a channel for turn not elastic
time-effective questions on long-time action to disposal of elastic questions is opened.Through the
calculation and comparison of examples physical meanings of the methods in this paper are explicit,the
accords of the results are good.
